    A ______________ is a magnetic needle that is free to turn.

    • Magnet

    • Compass

    • Bar magnet

    Correct Answer
    A. Compass
    Explanation
    A compass is a magnetic needle that is free to turn. It aligns itself with the Earth's magnetic field, allowing it to point towards the Earth's magnetic north pole. This makes it a useful tool for navigation and determining direction. Unlike a magnet or a bar magnet, a compass is specifically designed to be a magnetic needle that can freely rotate, making it an accurate and reliable instrument for finding direction.

    What would the field between three south poles look like?

    • All the lines would repel.

    • All the lines would attract.

    Correct Answer
    A. All the lines would repel.
    Explanation
    The field between three south poles would look like all the lines repelling each other. This is because like poles repel each other, causing the lines of the magnetic field to spread out and move away from each other.

    When a strong north pole is brought near material, the magnet attracts the __________ poles in each magnetic domain.

    • North

    • South

    • Electron

    • Atom

    Correct Answer
    A. South
    Explanation
    When a strong north pole is brought near a material, the magnet attracts the south poles in each magnetic domain. This is because opposite poles attract each other according to the laws of magnetism. So, the strong north pole will attract the south poles in the material, creating a magnetic attraction between them.

    The north pole of the compass needle points toward Earth's north pole in the ____________ Circle.

    • Antarctica

    • Arctic

    Correct Answer
    A. Arctic
    Explanation
    The north pole of a compass needle points towards Earth's north pole in the Arctic Circle. The Arctic Circle is the region located at a latitude of 66.5 degrees north, encompassing the Arctic region. This is where the Earth's magnetic field lines converge towards the north pole, causing the compass needle to align with the magnetic field and point towards the Earth's north pole. Antarctica, on the other hand, is located in the southern hemisphere and does not have the same magnetic alignment as the Arctic Circle.

    What will happen if you break a magnet in half?

    • It will just break in two, but will still have a north and south pole.

    • It will just break in two, but the poles will now be separated.

    • It will just break in two and you have to magnetise them.

    Correct Answer
    A. It will just break in two, but will still have a north and south pole.
    Explanation
    When a magnet is broken in half, each piece will still retain its own north and south pole. This is because the magnetic properties of a magnet are inherent to its material composition, specifically the alignment of its magnetic domains. Breaking the magnet does not alter the alignment of these domains, so both halves will continue to exhibit magnetic properties with their respective poles.

    The Earth's magnetic field is called what?

    • Magnetosphere

    • Magnetite

    • Magnetic force

    Correct Answer
    A. Magnetosphere
    Explanation
    The Earth's magnetic field is called the magnetosphere. It is the region surrounding the Earth where the planet's magnetic field interacts with the solar wind, a stream of charged particles emitted by the Sun. The magnetosphere acts as a shield, protecting the Earth from harmful solar radiation and charged particles. It also plays a crucial role in the formation of the auroras and the navigation of migratory animals that rely on magnetic cues.

    A group of atoms with their magnetic poles pointing the same direction is called?

    • North pole

    • Magnetism

    • Magnetic domain

    • South pole

    Correct Answer
    A. Magnetic domain
    Explanation
    A group of atoms with their magnetic poles pointing the same direction is called a magnetic domain. In a magnetic domain, the individual atomic magnets align themselves in a coordinated manner, resulting in a macroscopic magnetization. This alignment creates a magnetic field, which is responsible for the magnetic properties observed in materials.

    What is a force?

    • Electricity

    • Magnetism

    • Magnetic field

    Correct Answer
    A. Magnetism
    Explanation
    Magnetism is a fundamental force that arises from the movement of charged particles. It is characterized by the attraction or repulsion between magnetic materials. A force, in general, is a push or pull that can cause an object to accelerate or deform. In this context, magnetism can exert a force on objects, attracting or repelling them based on their magnetic properties. Therefore, magnetism can be considered a type of force.

    A group of atoms with aligned magnetic poles is called what?

    • Magnetic domain

    • Magnetic field

    • Magnetic force

    Correct Answer
    A. Magnetic domain
    Explanation
    A group of atoms with aligned magnetic poles is called a magnetic domain. In a magnetic domain, the magnetic moments of the atoms are all pointing in the same direction, creating a region of uniform magnetization. This alignment of magnetic poles allows for the formation of a magnetic field within the domain. Magnetic domains play a crucial role in the overall magnetic behavior of materials, as they determine the macroscopic magnetic properties such as magnetization and magnetic susceptibility.

    What are the two ends of the magnet called?

    Correct Answer
    poles
    north and south pole
    south and north pole
    Explanation
    The two ends of a magnet are called poles, specifically the north pole and the south pole. These poles have opposite magnetic properties, with the north pole attracting the south pole and vice versa. This is a fundamental concept in magnetism and is used to describe the behavior of magnets and their interactions with other magnetic materials.

    It weakens as you get farther from the magnetic poles is what?

    • Magnetic field

    • Magnetite

    • Magnetic force

    Correct Answer
    A. Magnetic force
    Explanation
    The correct answer is "magnetic force." The magnetic force refers to the force exerted by a magnetic field on a magnetic object. As you move farther away from the magnetic poles, the strength of the magnetic field decreases, resulting in a weaker magnetic force. This is because the magnetic field lines spread out and become less concentrated as you move away from the poles. Therefore, the magnetic force weakens as you get farther from the magnetic poles.

    Instead of using compasses, some animals have tiny pieces of magnetite in their brains.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Some animals have tiny pieces of magnetite in their brains, which allows them to sense the Earth's magnetic field. This ability is known as magnetoreception and is used for navigation and orientation purposes. Magnetite is a magnetic mineral that can align with the Earth's magnetic field, providing animals with a sense of direction. Therefore, the statement is true.

    When a strong magnet is held close to material, each magnetic domain lines up with the what?

    • Magnet's field

    • Magnetism

    • Poles

    Correct Answer
    A. Magnet's field
    Explanation
    When a strong magnet is held close to a material, the magnetic domains within the material align themselves with the magnetic field of the magnet. This alignment occurs because the magnetic field of the magnet exerts a force on the magnetic domains, causing them to line up in the same direction. Therefore, the correct answer is "magnet's field".

    Magnetic force acts through what?

    • Magnets

    • Magnetism

    • A magnetic field

    Correct Answer
    A. A magnetic field
    Explanation
    Magnetic force acts through a magnetic field. A magnetic field is a region in space where magnetic forces are experienced. Magnets and magnetism are related to the production and interaction of magnetic fields, but the magnetic force itself acts specifically through the magnetic field.

    It affects only objects that have magnetic domains is what?

    • Magnetic force

    • Magnetic field

    • Magnetoshpere

    Correct Answer
    A. Magnetic field
    Explanation
    A magnetic field is a region in space where magnetic forces are exerted on objects that have magnetic domains. Magnetic fields are created by magnets or by the flow of electric current. The statement suggests that the phenomenon being described only affects objects that have magnetic domains, which is consistent with the concept of a magnetic field.
